Took the top off the gear box and all those looking in were surprised at how good the gears looked with no obvious wear at all. The gear lever was freed up with a bit of WD 40, a file, and some hammering. The selector forks don't line up correctly to allow forward and backward movement of the selector rod with out some encouragement from a big screwdriver. Not sure how to aline them but will spend a bit more time looking at that. I can now get neautral and top gear but the low speed and reverse gear has to slide on a spline and it is siezed. Not by rust but probably just old dry oil. I have decided not to fix the brakes, they are not on and as the tractor only does 6 miles per hour flat out I doubt they will be needed as the few short drives it will hopefully make are not on steep hilly country. To fix the brakes I need to remove the rear wheels and apart from the weight of it all the very large nut is recessed and would need a very big socket and I imaging a lot of pressure to undo it, as it is all rusty and painted over. May be I'll relent at some point and do them. The engine still sits there, defying my efforts to be disassembled any further. The bent steering column has been removed. It is a worm and gear device and the shaft that connects to the gear is also siezed. On Monday I have a trip with my tandem trailer to pick up another dray for the wheel wright. So one does get roped into other side issues.
